Itching mood goes from day to night, and the head relaxes to think.
The next day, we decided to mail Adsense so we wnt straight to the Adsense help center and wrote ads not showing our site.

Few hours later they replied

"Hi,
I hope that you had a nice weekend and I am sorry to hear that your ads are not showing.

I reviewed extremecodez.com and was able to see ads on your site (see attached screenshot). I recommend ensuring JavaScript is enabled within your browser and ad-blocking software is disabled. Additionally, be sure to clear your browser cache and delete your cookies before trying to access your site again.

If you are still having issues, could provide the following information:
Screenshot of page(s) without ads
Exact URL(s) where you are not seeing ads
What browser version are you using?
Has anyone else experienced this problem or have you tried viewing the ads from different devices?
Have a great day :),
Harvey"

That was their reply and we did that actually it contribute to the problem too.

But here are some things that are not right which causes this problem also

Site visits are relatively few and most visitors come from social media Facebook.

Properly submitting the site to Google search console but duplicate some content and change the name repeatedly due to Robot.txt.

Adsense ads.txt Many people did not add to the blog's monetization options, which is a big reason.

Prevent invalid traffic.

Avoid using one adsense on different sites/block.

Site visitors comes from social media it good but not good enough try getting real visitors from Google searchsearc, mean while you can set up SEO for your blog/site.

Prevent invalid traffic you can read Google invalid traffic to understand their policy this can also get your Adsense account disabled or ban. Also limitations of your ads serving according to their new policy.

Robot text blocks should be avoided as fast as possible, but in the new version of Google search console, it has become very difficult.

Earlier, this block or Crawl error problem could have been solved easily with the webmaster, but there is no reason to worry that it will be solved within a few days with the update of the search console.

Regularly write good content so that the minimum visitor comes from Google, this will also solve the problem.

Remove all ads code from your site/blog for 2days so that your Adsense account can reset to regain good quality traffic.

After 2days, remove the previous ads in the Adsense ad unit, customize the new ad and place the ad on your blog/site.
